Sorry for the delayed reply, we were having serious flooding in chennai, india.
I tried what you said and get this error: archive contains no configuration file.
Also:
Tried using the same tar.gz file as a template and created a new container (in a zfs volume). The creation happened without errors. But the CT refused to start. I had made a mistake in the tar.gz as it retained the folder structure on the suse machine. the true-root was inside "/root/lxctest". I therefore moved all files from there to the correct root and then tried again:
The ct refused to start saying "missing os-type".
I added "ostype = suse" int the conf and tried again.
This time the error is: "TASK ERROR: implement me at /usr/share/perl5/PVE/LXC.pm line 1069".
Now I am stuck.
